S-97985A630 17.3 mm ID x 26 mm OD DIN 6797 External-Tooth Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance through external tooth design that bites into mating surfaces, preventing loosening under dynamic loads
• Enhanced corrosion protection with zinc-plated steel construction, extending service life in industrial environments
• Precise dimensional accuracy with 17.3mm ID and 26mm OD ensuring perfect fit for M16 fasteners
• Optimal hardness performance at Rockwell C35 providing durable teeth that maintain locking capability through repeated use
• Reliable compliance assurance meeting DIN 6797 standards for consistent quality and interchangeability
• Environmental responsibility with RoHS 3 and REACH compliance for safe use in regulated industries
• Maximum surface contact through external tooth placement distributing load evenly and minimizing surface damage

Professional Applications & Engineering Value

This M16 external tooth lock washer delivers critical vibration-resistant performance in demanding industrial applications where fastener security is paramount. Engineered to DIN 6797 standards, the zinc-plated steel construction provides both corrosion resistance and mechanical strength, while the external tooth configuration ensures maximum bite into both the fastener and mating surface. The precisely controlled Rockwell C35 hardness maintains tooth integrity through thermal cycling and mechanical stress, preventing the common failure of flattened lock washers. Ideal for machinery, automotive assemblies, and heavy equipment where vibration-resistant washers must maintain clamp load indefinitely, this solution addresses the critical need for reliable fastening in high-vibration environments without requiring additional locking compounds or complex installation procedures.

Specification Summary & Compliance

This precision metric lock washer features dimensional specifications of 17.3mm internal diameter, 26mm external diameter, and 1.0-1.4mm thickness, engineered specifically for M16 fasteners. Manufactured in compliance with DIN 6797 standards for external tooth lock washers, ensuring dimensional accuracy and performance reliability. The product meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) regulations (updated January 17, 2023, 233 SVHC), confirming environmental responsibility and chemical safety for industrial applications worldwide.
